Although ammonia is a very useful chemical ingredient for fertilizer and pharmaceutical product, recent researches have suggested it as one of sources of secondary fine dust in rural areas and the amount of gas should be reduced to protect human’s health. To effectively diminish the gas, several porous materials have been investigated, but most porous materials have low working capacity with type I isotherm due to high adsorption enthalpy. In contrast, an adsorbent with S-shaped gas isotherm can exhibit high working capacity in pressure-swing adsorption process. On the best of our knowledge, the adsorbent has been not explored. Herein, we synthesize and analyze a new hydrogen-bonded organic framework that can adsorb NH3 uniquely in an S-shape fashion. The framework can be easily regenerated at room temperature with recyclability in pressure-swing adsorption protocol. Detailed experimental data and explanations will be given in the presentation.
